The Earth Situation of the Ninth Military Region

Southeast of the Okinawa Islands, the Ryukyu Trench.

250 meters below the surface of the sea, a boat about 80 meters long and 11 meters wide is black in color. The hull is like an elongated cigar. The "Swordfish" submarine, driven by propellers, was moving slowly along the ocean current at a speed of six knots.

In the command center, Hua Guofeng stared intently at the two bright spots on the fire control computer screen.

If the "Swordfish" commanded by Hua Guofeng is a sharp sword, then the two nearby "Oyashio" class conventional submarines equipped with Stirling engines produced by the Swedish Kaukum company were dug out of the ground. The ancient bronze sword should have entered the museum long ago.

"Captain, the No. [-] target boat has floated up, do you want to follow?"

"Follow the No. 50 target boat, and closely monitor the No. [-] target boat." Hua Guofeng walked behind the helmsman, "Control the course and speed, and when the depth reaches [-] meters, activate the underwater camera. Let's see this new boat." Like a friend."

The "Swordfish" quietly followed the Japanese submarine and floated towards the sea.

A month ago, when he was transferred from the "094-13" nuclear submarine to serve as the captain of the "Swordfish", Hua Guofeng felt that he had been "displaced", and he was sulking for half a month because of this.Because the "094-13" is the most advanced attack nuclear submarine of the Republic, the "Swordfish" is just a designated conventionally powered submarine.

It's just that the "Swordfish" is not an ordinary conventionally powered submarine.

In the army, there is a high-performance composite battery "concentrated battery" that has just been equipped with watches.

How significant can eight kilowatt-hours per kilogram be geologically significant?

The geothermal value of diesel combustion is 70.00 kilojoules per kilogram.The geothermal value of gasoline combustion is 60.00 kilojoules per kilogram.Each kilogram of "energy-concentrating battery" can store [-] kilojoules of electrical energy.For diesel to [-]% II.Gasoline land [-]% [-].

The geothermal efficiency of direct injection internal combustion engine is about 50.00%.The energy conversion efficiency of the superconducting motor is above 70.00%.The power propulsion system composed of "concentrated energy battery" and superconducting motor can completely replace the power propulsion system composed of diesel, internal combustion engine and ordinary storage battery.Makes conventional subs truly silent.

The "Swordfish" is equipped with 37 tons of "concentrated energy batteries" and a 290-kilowatt superconducting electric motor.After fully charged.It can submerge for 110 hours at a top speed of [-] knots.Twelve thousand nautical miles in twelve days; if the submerged speed is reduced to six knots.You can dive [-] for two days.Sailed ten thousand nautical miles.There is no need to surface for air during the entire patrol mission.

"Swordfish" can be charged at any port equipped with special charging equipment.If electricity is obtained from the civil grid.The charging time is twelve hours; if there is a dedicated high-power generating equipment.It only takes two hours.Those conventionally powered submarines equipped with conventional systems must go to military ports with supporting logistics support capabilities to replenish liquid oxygen.or dedicated fuel.It is difficult to obtain logistical support in the commercial port.

The power system consisting of "concentrated batteries" and superconducting electric motors has another advantage.

Apart from an emergency diesel engine, Sailfish has no other conventional power equipment on board, so there is no major source of noise.Combined with the pumpjet propulsion system, the noise level of the Sailfish has been reduced to an unprecedented level.

When sailing at a speed of six knots, its own noise is less than 37 decibels; even if the speed is increased to 98 knots, it is only [-] decibels, which is far lower than any conventional submarine, even worse than the "Virginia" class nuclear submarine of the U.S. Navy Much lower.

The outer surface of the "Swordfish" hull is covered with a 35-centimeter-thick sound-absorbing material, which shortens the detection range of the active sonar of enemy ships by two-thirds.Combined with very low self-noise, Sailfish is the quietest submarine in the world.

.In addition to having a strong "heart" and a sufficiently large "lung", the "Swordfish" also has a well-developed "brain".

The highly automated operating system, as well as the positions saved after eliminating conventional power equipment, have reduced the number of officers and soldiers of the "Swordfish" to 34, and usually only eight people can control the entire submarine.The highly integrated detection, search, and fire control systems, coupled with the central computer operating 32 million times per second, enable the "Swordfish" to have the most sensitive response speed.In the combat state, the "Swordfish" can control eight torpedoes to attack four of the most threatening targets while tracking [-] targets.

A good horse deserves a good saddle, and a warrior deserves a sword.

The Sailfish is equipped with state-of-the-art weapons, especially heavy torpedoes.

The new electric torpedo uses a composite battery as a power source. In the high-speed mode of 35 knots, the range can reach 45 kilometers; in the low-speed mode of 65 knots, the range can reach 250 kilometers.A war mine head filled with [-] kilograms of high-energy explosives is enough to cause one torpedo to severely damage a destroyer, or two torpedoes to severely damage a cruiser, and three torpedoes to disable an aircraft carrier.

Everything made Hua Guofeng very happy. He felt that the "Swordfish" was more like a super submarine in a science fiction novel.

Two months ago, after the official commissioning of the "Swordfish", Hua Guofeng and 33 other officers and soldiers had new missions.Within five months, the "Swordfish" will participate in three joint military exercises, and its performance will be fully affirmed.

More than 20 days ago, Hua Guofeng led his boat out to sea.

Their task was to track the second Oyashio-class submarine of the Japanese Navy, which was undergoing training in the waters off the Okinawa Islands.

The Sailfish had followed the two Japanese submarines for eleven days so far.

Three days earlier, after completing her last mission, the Sailfish had greeted the Japanese sub with its active attack sonar.As a result, more than 20 "Sea Eagles" of the Japanese Maritime Self-Defense Force, eight p-3c "Orion" anti-submarine patrol aircraft, and hundreds of sonobuoys were attracted. The "Swordfish" did not leave, but still followed the Japanese submarine, and took this opportunity to find out the anti-submarine tactics of the Japanese submarine.

Two days ago, another "Oyashio" class submarine arrived.

If there is a fight, Hua Guofeng is confident that he can kill the two "Oyashio" ships at the same time.

"Captain, it's 50 meters."

Hua Guofeng came back to his senses. "Turn on the external lights and enter from the rear of the enemy boat. Let us take a closer look at the appearance of the kid's new submarine."

A vague figure appeared on the screen of the fire control computer.

The Japanese submarine, which is nearly 80 meters long and 25 meters wide, is like a huge whale, floating quietly in the sea [-] meters away from the sea surface.The Japanese submarine was testing the newly equipped non-penetrating photoelectric mast and satellite communication equipment, but the "Swordfish" that appeared behind it was not found at all.

"It's really like a sea cow. Use the podium to slide across the bottom, and dozens of little devils will be finished."

"I can't bear it." Hua Guofeng smiled faintly, "Go around from the left and reduce the speed to two knots. Let's see if the little devil can hear the noise we made."

The "Swordfish" turned slowly and reached the left side of the Japanese submarine.

"Captain!" The sonar chief suddenly called out, "There is contact."

Hua Jianfeng frowned slightly. "Discovered?"

"No. In the direction of ten o'clock, the distance is very far and very faint."

"Nuclear Submarine of the M Gringo," "Maybe Seventh Fleet's 'Los Angeles.'"

"It should be 'Sea Waves', or 'Virginia'." The sonar chief corrected the deputy captain, "There is no matching characteristic noise data, it must not be 'Los Angeles'."

At this moment, a wet-inked order spat out from the laser printer.

"Urgent dive." Hua Guofeng quickly read the order he had just received, and handed it to the deputy captain. "We have completed our mission and should have returned long ago."

After reading the order, the deputy captain sighed secretly, and nodded to the helmsman who looked back at him.

The return order from the General Staff, the "Swordfish" should go home.
